In this paper, we develop an open quantum dynamics theory for the HH model, in which the HH system is coupled to baths consisting of surrounding atoms or molecules. Here, by an open quantum dynamics theory we mean a theory pertaining to a system that is further coupled to bath systems that are modeled by infinite numbers of harmonic oscillators.[1]}
Such system–bath models have been employed for investigations of electron transfer[2]} and exciton transfer processes[3]}, [4]} of a molecular system, in particular for calculations of the nonlinear optical spectrum.
However, the effects of on-site Coulomb repulsion between electrons, which plays an essential role in charge transfer complexes, has not been investigated in any great depth.
